A penny for your thoughts

While Casey was waiting in line, the homeless man walked into the establishment. He was counting the loose change in his hand in order to pay for his meal.

The college student decided to try and spark up a conversation, although it seemed as if the man wasn't interested in talking. Realizing that he only had about a dollar in change - Casey bought him a bagel and coffee. She then invited him to join her at a table to eat.

He shared his heart

Over their meal, Casey learned a great deal about the man named "Chris." He shared how he had never known his father, had lost his mother to cancer, and how drugs had changed him into a person he despised - although he wanted to be someone that his mom would've been proud of. Chris also expressed how people usually treated him unkindly because he was homeless.

Although they were former strangers, the pair sat at the table for a long time...simply talking.

One final message

When it became time for Casey to head back to school for a class, Chris asked her to hold on for a moment. He then took out a crumpled receipt and jotted a note onto it. Her new friend smiled, handed her the paper, and left the restaurant. It was at this point that Casey read his written message...

Words she'll never forget

Casey was taken back by Chris's scrawled message, which said:

"I wanted to kill myself today. Because of u I now do not. Thank u, beautiful person."

If it had not been for Casey's random act of kindness, that day may have turned out very differently for Chris... Being very affected by the emotional experience, Casey decided to share it on her Facebook page. You can read her entire post below.

today I went to Dunkin and saw a clearly homeless guy singing on the side of the road and picking up change. Eventually...

A powerful experience gone viral

Initially, when Casey first made the Facebook post - it was read by her friends, family, and those who it was shared with. However, it was after Love What Matters posted the young mother's message on their page that it went viral. In a short amount of time, her story has collected more than 740,000 likes and 220,000 shares on their page.
